METHOD or A'JPTAOHING LABELS on THE LIKE.

No Drawing.

To all whom it may concern:

Be it known that I, HARRY AYLIFFE, subject of the King of Great Britain, residing at 90 Woodside Green, London, S. E. 25. England, have invented certain new and useful Improvements in Methods of Attaching Labels or the like, of which the following is a specification.

This invention relates tomethods of attaching a label for ornamentation or otherwise to a surface, and particularly refers to the labelling of boxes formed from sheet metal, for instance, inking pad receptacles.

The main object of the present invention is to obtain a means of fixing a label so that an artistic result obtains.

Another object is to provide a fixing means for labels which is of lasting character.

Another object is to obtain a method of fixing which results in the label being protected from the atmosphere, and a particular object is to provide a means of fixing a label to an ink pad or like tin having all the advantages stated above, and which is further protected against accidental removal.

According to the present invention, a sheet duly ornamented or printed on is attached to the required surface by carrying out the following steps Coating the surface with a varnish, smearing the sheet with a softening agent for celluloid, pressing a film of celluloid over the smeared sheet, further pressing the celluloid-covered sheet with the application of heat, and finally pressing the sheet so treated on to the surface, the said final pressing operation being accompanied by the application of heat.

The pressing of the sheet and celluloid film may be effected by heated rollers of the ordinary character found in printing establishments, and the softening agent-which may be methylated spirit-having slightly softened the under-surface of the celluloid film, the pressure under heat causes absolute adherence of the sheet and the film so that they are inseparable.

The attachmentof the label so formed to the surface where it is wanted may be achieved by applying heat if the said surface is already coated with a varnish, as is usually the case when dealing with coloured tins, or by applying a thin layer of varnish d rec ly on. he sa d rfaqe 91 Ov r a 991011. 2

layer applied thereto where not already of such a character as to be affected by heat. The heat may be applied in either case by means of a stamp press with a heated die, it being important that the heat shall not be so high in temperature as to reduce the polish ofthe celluloid film. The methylated cardboard or paper'surfaceto which printing has been appliedis placed with the varnlsh surface under the heatedx'die. of a stamp press and pressed over two or three" seconds, upon which complete adherence to the said surface is achieved.

The surface to which the label is to be at tached is preferably larger than the label, and in the case of a tin box particularly for stamp pads, the pressing die is formed so that the process results in causing a slight depression or recess in the surface of the lid which has to be occupied by the celluloid and paper label. By careful attention to detail a very artistic and useful result is obtainable, which is substantially permanent in practice, since the edges of the label'are protected by the border to the recess against the possibility of being raised at the corners, as is the case with a label pressed on a flatsurface.

In the particular case of the box for a stamp pad, the base colour of the tin is applied by a. machine which finishes the same off, either with an admixture of varnish and the colour, or by a second coat of varnish applied on the colour layer. In either case, the said surface can be made thoroughly adhesive by means of heat coming from the hot die, and perfect adherence is obtained thereby.

I claim r 1. Method of attaching a sheet to a surface, consisting in coating the surface with varnish, smearing the sheet with a softening agent for celluloid, pressing a film of celluloid over the smeared sheet, further pressing the celluloid-covered sheet with the application of heat, and finally pressing the sheet so treated on to the surface, the said final pressing operation, being accompanied by the application of heat.

2. Method of attaching asheet to a surface, consisting in coating the surface with varnish, smearing the sheet with a methylated spirit, pressing a film of celluloid over the smeared sheet, further pressing the celheat, and finally pressing the sheet so treated on to the surface, the said final pressing operation being accompanied by the application of heat. 7

3. Method of attaching a sheet to a surface larger than the sheet, consisting in coating the surface with varnis h, smearing the sheet with a softening agent for celluloid, pressing a film of celluloid over the smeared sheet, further pressing the celluloid-covered sheet with the application of heat, and finally pressing the sheet so treated onthe said surface so that the surface is recessed, thesheetbecoming protected by the b'ordering face of the'said surface, the said final pressing operation being acc oinpanie'dby the application of heat.

4. Method of attaching a'paper label to surface formed from sheet tin larger than the label, consisting in applyin'gto the surface aicolour layer and a Varnish,smearing the'label with a softening agent for celluloid, pressing a filinbf celluloid over the smeared sheet, further pressing the celluloid-covered sheet with the application of heat, and finally pressing the label so treated on to the surface, the said final pressing operation being accompanied by the application of heat.

5} Method of attaching a paper label to a surface formed from sheet tin larger than the label, consisting in applying to the surface a colour layer and a varnish, smearing the label with a softening agent for celluloid, pressing a film of celluloid over the smeared label, further pressing the celluloid-'covere'd'label with "the ap'plicatio rof;

heat, and finally pressing the label so treated on the said surface so that the surface is recessed, the label becoming protected by the bordering face of the said surface, the said final pressing operation being accompanied by the application of heat. l 'i In testimony whereof I affixiny signature.
